Application filed April 30,

To all whom may concern:

Be it known that I, EDWARD E. BLACK- BURN, a citizen of the United States, residing at Marion, in the county of Grant and State of Indiana, have invented certain new and useful Improvements in StoveDoors, of which the following is a specification.

My invention relatesto stove doors and one of the objects of the invention is to provide in a device of this character, a construction for mounting the high closet doors in a cooking range so that they will not show any nuts or bolts, lugs or catches when the doors are closed or when they are lowered to open position.

A further object is to provide a concealed hinge construction applicable to the lower side of an oven door, which will securely hold the door in horizontal position when open, which is strong and simply construct: ed, easily assembled and which is not liable to get out of order.

With these general objects in view, my invention consists in certain novel and peculiar features of construction and combina tion of parts as hereinafter described and particularly pointed out in the claims, refer ence being had to the accompanying drawing in which similar characters of reference indicate similar parts.

Figure 1 is an elevation showing my invention as applied to the high closet of a cooking range;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a section on the line 3-3 of Fig. 1;

, Fig. 4: is a section on the line i -4: of Fi 2' I Fig. 5 is a fragmentary perspective view of the rear side of a door showing the hinge lu and,

Fig. 6 is a fragmentary perspective view of the door frame.

Referring more particularly to the draw ings, 1 is the hi h closet of a cooking range, comprising a door frame 2 secured to the oven frame by bolts passing through holes in suitably disposed lugs 3 and also through holes 1 in the'flanges 5, located on the inner side of the door frame andthus being effectually concealed from view in the finished article.

The door frame is shown herein as cast in 1921. Serial No. 465,793.

one solid piece-toprovide openings for two doors and i, and comprisesend uprights 8. a center upright 9,, a horizontal top member 10 and a horizontallower member 11. This lower member is provided along its outer upper edge with a curved groove 12, which cooperates with the curved lower end 13 ofthe door, thelatter being laterally extended to provide pintles 21 provided with lugs 14, which are adapted tocontact with the inner side of the upright members of the door rame and to act as limiting stops when the door is in open position. The groove as thus members contact with the lug on the hinge,

they may be provided with concavities to snugly fit the cam shaped lugs.

The door frame may be set at angle so that when in closed position it will rest against webs 15, thereby dispensing with the neces-.

sity of springs or catches for holding it in closed position.

The door is cast in one piece to provide an open frame work in which is secured a suitable panel 16, and for operating the door, a knob 17 is secured to the said frame work.

In placing a door in position in the frame, it is merely necessary to pass it through the door opening at a suitable angle and drop the lower end into the roove 12, where it fits loosely. The lower on of the door will then be held against translational movement inwards, by the ridge or abutment 18 and outwards, by the vertical uprights of the door frame. The advantage of this construction is that when both opened and closed, there are no projecting lugs or slots to be seen and which adds materially to the appearance of the finished article. The construction also permits the same door to be used in right and left hand positions.

From the above description it will be apparent that I have produced a device of the character described, which possesses all the features enumerated as desirable, and While I have illustrated and described the preferred form of the invention, it will be understood that I reserve the right to all changes properly falling within the scope and spirit of the appended claims.

Therefore what I claim as new and desire to secure by Letters Patent is:

1. An oven having a door frame comprising a bottom member and an upright memher, the said members being provided with a bearing, that portion in the upright member opening on the inner side of the frame, a door plvotally mounted in the said bearing and having a stop for cooperating with the inner side of the upright member for holding the door in open position.

2. An oven having a door frame, comprising a bottom member and upright members, the bottom member being provided with a bearing, the upright members being open on their inner sides, an abutment defining the inner side of the bearing, a portion of the upright members defining the outer side of the bearing, a door pivotally mounted in the bearing andengaging the abutment to limit inwarc translational movement thereof and pintles carried by the door for engaging the upright members to limit outward translational movement thereof.

An article of manufacture, a metal door frame, comprising upright members open on their inner sides, a bottom member provided with a longitudinal hinge groove having a vertical abutment on the inner side which terminates short of the upright members.

4. An article of manufacture, a metal door frame comprising upri ht members and a bottom member, a longitudinal hinge groove defined on the front solely by a part of the upright members and on the rear by a part of the bottom member.

In testimony whereof I atlix my signature.

EDWARD E. BLACKBURN.
